This invention relates to heat exchangers fr reference toa deviceespecially designedfor increased r reduced in accordance" with thecooling lubricating oils.

The primary object of the inventionl isto provide a cooling deviceorsrhejatezcchanger of the above type which is made up of a series ofplates whose size and/or number may be desired installation and whichembody fetures of construction which render the device unusuallyefficient in operation. n

With the "foregoing object in view., the plates of the device are ofsimple construction .and interchangeable, and providedwith ymeanswhi'ch, among other advantages, permit` convenientdrainage andcleaning of the devicewhile in assembled condition, reduce the pressurein the device by eliminating congestion of fluids circulatingtherethrough, servey to direct the course of the'cooling Huid in itstortuous path, equalize the head pressure of the cooling Huid, andalsoeliminates.

the necessity for by-pass connections for. any excess cooling iuid thatmay Abevpresent in the cycle.im A' 4 i A rFhe various features ofnovelty and advantage resident in my improved heat exchanger will becomemore apparent in View of the following descriptive matter taken inconjunction with the drawings, wherein :---v

According to the present invention, the device comprises a plurality`oi."V l intermediate units or plates, each being identicalpin convstruction vwand theregore interchangeable together with a pair o endheads or plates both of which areidentical in construction and :roHOMEB. E.

is provided on the side 7 of the plate an arcuate boss orrib 11 providedwith an arcuate slot `or port 12.y (See Figure 4.) Between one of thesaid Aadjacent lugs 9 and a next adi' jacent lug 9 there is formed inthe plate an arcuate slot or port 13. On the opposite side ofthe plate,thatis, on-the side 8 and opposite the slot 13 there is provided betweentwo ad-f" jacent lugs 10 and integral with said lugs l() an arcuaterboss orv rib-14. i

The boss 14 is disposed at, what, for the sake of convenience may betermed the top part of the plate while the' boss 11 is disposed at oneside of the plate. i

0n theside 8 of the plate diametrcall opposite the boss 14, a lug 15 isprovided having an orice 16 formed therethrough and opening on oppositesides ofthe plate. This orifice 16 has a number of advantageousfunctions, as will hereinafter appear, and

drop or luy-pass orice.

In assembling the plates, the plates have corresponding faces disposedin opposed relation formingalternate shallow and deep chambers I17 and18 respectively, while to -put the chambers in alternate communicationso that the shallow chambers communicate one with another, vand the deepchambers do likewise, each plate is set a half of avice in an alternatemanner. Theyportsvliz communicate the chambers 18 at the top and bottoman` alternate manner. {Asfisf also i manifest, the oriices 16communicate the chambers 18 at the top and bottoml of the de'- vice inan alternate manner. s t' From the foregoing, it will be seen, that the'oil kor other Huid to be cooled entering thel irst chamber 17 throughportsf12 on one side of the device will flow across'the chamber 17 topass through registering' ports 12-12 on an opposite side owthe deviceto enter the next chamber 17. t

Y The water, or other cooling mediumenter- I ing the first chamber 18,flowing through Athe first pair of registering ports l3--13,.Will

' End plates 19`are provided and have.

formed integrally therewith an inwardly directed peripheral iiange 20.0n their inner faces, the end platesV` 19 are each provided with lugs 21radiating inwardly and arranged in 'circumferentialspaced relation.These lugs are suitably apertured for registry with the apertured lugson the intermediate plates 5. The several intermediate plates 5 f andsaid end plates 19 are secured together by rods 22y passingthroughfthelugs 9,'10 and .21. Nuts 23 are threaded on the ends of therods 22.

v Between two adjacent flugs 21 there is formed integrally therewith andwith the plate 19 an arcuate boss 24 havin an arcuate recess `or port25.formed thereln. Com- 'the apparatus is put.

municating with the recess 25 is an oil orifice 26. The end plate,,within the confine'sof .A l

in the system or cycle' above that required for its rim 20 -intransverse alignmentwith the oil orifice 26 is provided with arelatively large water port or openingI 27. u In practice, then.. itwill be seen that oil entering through the orifice 26 of oneend platewill flow through thechambers 17 to discharge from the device thru a theopposite e'nd` of the device. Likewise water will enter the firstchamber 18 through the water port 27 infone end plate and iow. inalternate directions through the chamber u 18 to discharge from thedevice through the water orifice 27 in the end end ofthe device. 1 Y

Each of the end plates on 'a corresponding xside thereof is providedwith suitable,y atplate at the ether .taching brackets 29 whereby theapparatus may be secured t'o an engine or toyany suitablesupport'dependent upon the use to which On each face 7 and 8the platesare provided with studs or projections 30 and 3-1,

respectively, while on their inner faces the' end plates 19l are"likewisef providedl with studs or projections 32, to prevent buckling ofthe plates and to .further enable theplates Vto rwithstand. a highdegree of pressure.

like orifice 26 on the end plate 19 at "be subtracted from or added toat will.

release At the top and bottom thereof, the end plates 19 are providedwith suitable orifices 33, to align with the orilices16 at the top andbottom of the device, the said drain orifices 33 being normally closedthrough the medium of suitable plugs 3d.

It is thought that Vfrom the foregoing description, taken in connectionwith the accompanying drawings,- themany advantages of my improvedapparatus will be readily appreciated by those skilled in the art, as

well as the details of construction yand the fact that the apparatus isadaptable to be used for -a varietyof purposes.

Simply by removing theplugs 34, the water or yother cooling fluid may bedrained from all of the chambers 18 Whenfdesired, and

this may be done whether the device be disposed in a horizontal orvertical position or at an angle thereto. :These aligned orifices 16also serve to guide the Huid on into the next compartment and increasetheforce of flow While at the same time decreasing the pressure tin theexchanger by eliminating congestion of fluids atathe points Where thelatterreverses direction of'. flow. Furtherincre, any heavy-sediment orother mattertroduced through the holes 33, 16, to further clean thepassages Without removing any connection or piping or otherwisedisturbing the installation. s

` Another advantage of this aligned orificeand port construction is thatany excess fluid and which soon become'apparent with actual use of anexchanger builtin accordance with my inventlon,

construction 'and interchangeable and may The device' may be easilyassembled andA taken vapart and the plates are well braced by the llOThel plates of they exchanger are simple in particular arrangement ofstuds or projections 30, 31 and32.,

` Even though I have herein shown and described the preferred embodimentof my in- `vention, it is to be understood that the same -.-issusceptible to changes fully comprehended by the spirit of the invention'as hereinY described, and the scope of the appended claims. f
